TYPE-"WRITING MACHINE.

ocaosi.

To all whom it may concern Be it known that I, JOHN C.MoLAUo1-1Lm, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Typel/Vriting Machines, of which the following is a specification.

This invention relates to a new and improved paper depth gage for a typewriter and is an improvement on my application No. 688,331, filed April 3, 1912.

It is the purpose of this invention to provide a simple, substantial and accurate pap er depth. gage whereby the typist can determine at a glance how'close the bottom of the sheet is approached, and also whereby the typist can set a limit of approach to the bottom edgeleaving any desired bottom margin. In other words, it enables the typist to set a limit to the number of lines to be written on a sheet, and totell at. a glance when this limit has been reached.

It is further the purpose of this invention to provide a' gage which can be quickly detached when it is not desired to use the same and also which can be as readily snapped on into an operative position when it is necessary to use it.

In the present embodiment of the invention, the gage is shown to include a standard, attaching means and a stop. The standard is formed from a single strip of wire bent intermediate its ends to form an elongated loop with parallel reaches. The stop is adjustable along the standard and forms with the standard at the junction of the two, a stopping point for the top edge of the work sheet. When the work sheet comes in this position it is a signal that the predetermined limit of writing on the work sheet has been reached. The stop is resilient and formed to lock itself in its adjusted position on the standard by engaging with Two forms of attaching means are herewith shown, one in which the attaching part is integral with the standard, and in fact formed from the same strip of wire, and the other in which this part is formed from a strip of sheet metal. In both cases, however, the attaching means is constructed of spring material and formed so as to. readily snap into a'locked position, as by squeezing between the rail and the paper shelf on the platen frame.

In the accompanying drawings, Figure 1 is a vertical section taken from the front and rear of the top part of the typewriter, showing the gage in its attached position with the work sheet in a position corresponding to the writing of the last line of the typewritten matter. Fig. 2 is a fragmentary perspective view. Fig. 3 is a fragmentary view in front elevation showing the relation of the stop to the standard. Fig. i is a fragmentary vertical section on the line 4- 1 of Fig. 3, showing the stop in its locked position. Fig. 5 is a view similar to Fig. 4: showing the stop flexed against" the tension of the spring metal thereof, to assume its unlocked condition. Fig. 6 is a bottom plan view showing the relation of the stop to the standard in its locked position. Fig. 7 is a fragmentary rear view of a modified form of gage showing a modified means of attaching the gage to the typewriter. Fig. 8 is a fragmentary perspective view of the form shown in Fig. 7. Fig. 9 is a vertical transverse section of the form shown in Figs. 7 and 8.

Referring more particularly to the separate parts of this invention as embodied in the forms shown in the drawings, 1 indicates the typewriter or typewriting mechanism, only a part of which is, however, shown. The typewriter may include, as usual, a carriage having a platen frame 2, on which is ro-tatably mounted a platen 3 for supporting a work sheet 4. The work sheet 4 is struck by the type on the type-bars 5 when the latter are actuated in any usual manner by key mechanism, so that an imprint is made on the work sheet-at a point 6, which may be termed the printing point of the typewriter.

Inasmuch as it is desirable that the number of lines written on a work sheet shall be limited, or in other words, that the bottom line of the typewritten matter shall be dis' tant a certain amount from the bottom edge of the work sheet, it is necessary for the typist to know when this oint has been reached. The bottom ed e o the work sheet 4, however, is at this time generally concealed between the platen 3 and a paper shelf 7 which guides the paper to the platen. There must therefore be some outside means for enabling the typist to tell at a glance 1 advantages will herei i Eta when the limit of typewriting on a work sheet of a particular size has been reached. For this purpose, I provide a gage 8, which is mounted on the typewriter, preferably on the platen frame, in such a position that the top edge of the work sheet will be stopped from further movement when a predetermined limit of typewri-ting for the particular work sheet has been reached.

In the forms shown in the drawing, the gage is shown to comprise a standard 9, attaching means 10, and a stop 11, adjustably mounted on the standard ,9. The stop is shown to be constructed of a single strip of sheet metal having openings 12 and 13 arranged adjacent the ends of the stop, and athird opening 14 arranged intermediate the openings 12 and 13. The strip of metal is bent as will be'seen by reference to Figs. 4 and 5, so that the three openings 12 to 14 extend in alinement with each other, whereby the standard can be run through the three openings. It will also be noted that'the end openings are brought in juxtaposition to each other, while the intermediate opening 14 is somewhat more distant from either of the end openings. This arrangement gives to the stop a spring which'tends to cause the front edge '15 of the opening 12 to hug the standard 9. The arrangement also provides an extension 16 which forms with the standard 9 at the junction thereof, a stopplng corner in which the top edge of the work sheet will readily catch.

The standard 9, aswill beseen by refer ence to Fig. 2, is formed from a single strip of wire bent intermediate its ends to form an elongated loop having parallel reaches. These reaches are provided on their facing sides with notches 17 enabling the front margin 15 of the opening 12, which is cut away at the ends thereof, as wlll-be seen by reference to Fig. 6, to engage these notches and lock thestop 11 into any adjusted posi tion on the standard 9. These notches, may

if desired, be arranged at intervals from each' other corresponding to; the distance r between typewritten lines under the control of the typewriting mechanism.

6(L 21 on the platen In Figs. 1 and 2, the attaching means v10 is shown to be formed integral with the standard 9, in fact, constructed of the same strip of wire; that is to say, the reaches of the standard 9 are extended and bent to form loops 18, 19,'and 20, which extend in planes substantially at right angles to the plane of the loop forming the standard 9. These loops are somewhat springy so that the loop 19 can be readily sprung n between a rail ame 2, and a curl 22 on thepaper shelf 7.

The extremities of the wire indicated at 23 may engage the back side ofthe shelf 7 so as to form a steadying means, which together with the spring snap connection of 1 21 and the curl 22 in a similar manner.

ative position for the purpose of disconnec ting it from the typewriter.

The loops 18 may be secured together by a band orcollar 24 adding strength to the device as a whole. In the form shown in Figs. '7 to 9 inclusive, the attaching means instead of being formed inte ral with the standard 9, is constructed from a separate strip of sheet metal 26, bent to form loops similar to 'the loops 18, 19 and 20, and engaging the rziil n this case the ends of the wire forming the standard 9 are bent inwardly as at 24 to pass in a curl 25 formed in the sheet metal attaching means 26. The standard 9 is further secured to the attaching means 26 in this instance, by curls 27 and 28, embracing the reaches of the standard 9. The attaching means in this instance may be provided with an opening 29 to add to the resilientge thereof.

In the use of the'device a trial sheet is first marked at a point adjacentthe bot tom, where it is desired to limit the typewriting. The sheet is then run'in the typewriter until this mark comes to the prmt-' ing point 6. The stop is then manipulated by pressing on opposite sidesthereof, from the condition shown in Fig. 4, to that shown in Fig. 5, whereby it will be unlocked from the standard 9 so that it can be readily adjusted until the extension 16 thereof comes in contact with the top edge of the work sheet 4, as indicated in Fig. '1. In subsequent typewriting operatiohs, when the top edge of any sheet of thesame size comes in engagement with the .gage', as shown in Fig.

1, it will indicate that the'limit of desired typewriting on this particular work sheet has been reached.

When it is no longer desired to use the gage, or when it is desired to close the machine, it is merely necessary to force the gage rearwardly, when the spring loop 19 will ios yield s'ufiiciently' to enable the gage to be I snapped ofl of the machine. The gage, can- -just as readily be snapped into position by pressing the spring loops 19 between the rail 21 and the edge ofthe curl 22.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
